A further object of our invention is to provide I Attached to the tractor draw bar 2| is a bracket 22 to which is pivotally attached at 23 a pair of forwardly extending bar members 24. The members 24 extend forwardly with the point 25 to which is pivoted a gatheringmember which consists of the vertical upright members 25 bea device of this character which includes separate controlling means for pivoting the manure elevating device as desired and from any position to cause dropping of the load on the same by gravity.

A further object of our invention is to provide braking means associated with the device so that the brake can be applied in any position on the unit.

A further object of our invention is to provide means for powering the arrangement directly from the power take-oil on the tractor.

A further object of our invention is to provide a convenient method of controlling the tilting of the manure carrying fork conveniently from the seat of the tractor.

A further object of our invention is to provide a unit of this character which is in fixed position for operation at all times and which can be manufactured simply.

With these and other objects in view, our invention consists in the construction, arrangement and combination of. the various parts of our device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the arrangement as attached to a tractor,

Figure 2 is a forward .view of the same,

Figure 3 is a rear view,

Figure 4 is a detail of the braking mechanism,

Figure 5 is a modification, and

Figure 6 is a rear view of the tractor showing the mounting of the hydraulic modification shown in Figure 5.

We have used the character iii to designate the hood of a standard tractor and the forwardly extending steering rod I! which is attached to the member 12 which communicates with the member 13 which drives the spindle H for turning the front wheels 15. The 'lower framework of the tractor is indicated by the character IS with the usual power take-off pulley by the character 11. The'rear axle is indicated by the character I8 which is suitably geared to the rear wheels 19. The steering wheel is indicated by the character 20.

' the points 29.

tween which is attached the angled plate member 21 which extends forwardly a slight distance and attached to the member 21 are the forwardly extending tines 28 which terminate in The tines 28 are evenly spaced between the members 26 and are rigidly attached to the aforesaid member 21.

A further brace member 30 is attached between the members 28. Pivotally attached at 3| to the upright members 26 are a pair of further members 32 which are parallel to the members 24 and which members 32 extend rearwardly toward the rear of the tractor into the downwardly curved portion 33 and pivotally attached at 34 to the rear end of the members 32 are the spaced levers 35 which are attached at 36 to a shaft 31 which shaft is joiunalled in the brackets 38, which brackets are attached to the upper portions of the rear axle housing I8.

Attached substantially toward the center oi the shaft 31 at 39 is a further rearwardly extending lever 40 which is pivoted at 4! to a further downwardly extending lever 42. Pivotally attached at 43 to the lever 42 is a forwardly extending lever 44 which is solidly attached at 45 to a suitable shaft 46 which passes within the arcuate housing 41. The housing 41 includes a worm gear sector which meshes with a worm which is mounted within the casing 48. The worm within the casing 48 is attached to a steering post 49 which is attached to the horizontally positioned steering wheel 50 to which is attached the small handle 51. Suitable brackets 52 and 53 support the latter arrangement.

The seat of the tractor is indicated by the character 54. Attached at the forward end of the framework 16 of the tractor at 55 are a pair of vertical upright members 56 which pass upwardly and are attached to the top cross bar 51 and a pair of further members 58 are spaced apart from the members 55 and are attached at 59 to the cross bar 51. The members 58 include the outwardly extending portions 60 at the bottom thereof which are adapted to prevent the bars 24 from jamming between the members 58.

J oumalled within the members 56 is a shaft 6| to which is attached the reel member 62 upon which is suitably wound the pair of cables 53 which are attached at '64 to the transversely exf plied by pulling the cable I5. lever I3 to be swung about the pivot 18 thereof gear 68 which meshes with a smaller gear 88 which is attached to a further shaft 81. The shaft 61 is journalled in the members 58 and is attached to the pulley 88 and at the other extremity to a brake drum 88. The brake drum 88 is enclosed by a brake band I8 which brake band is secured at II to a, suitable bracket I2 (see Figure 4) which bracket is attached to the member 58.

Attached to the lever I3 at I4 is the cable I! which passes rearwardly to the driver of the tractor. The lever I3 is suitably pivoted at I8 and the upper end of the lever I3 is pivoted at 11 to I the brake band III. A drive belt I8 passes over ure 2)f are attached across the lower ends of the members 58 and 58 to help brace the same. Now that the structure of our invention has been explained, we shall explain the operation,

thereof.

It will be observed that the tractor can be driven with the entire arrangement in working position and at the first portion of the operation as shown in Figure 1, the tractor is driven forwardly and the tines 28 which are horizontally positioned can be driven into the manure and below the same at the ground level. The pulley I1 is then operated through the usual clutch means which causes the upper pulley 88 to be rotated due to the connection through the belt I8. This drives the shaft 81 which in turn through the enmeshment of. the gears 88 and 65 drives the shaft 8| which causes the cables 83 to bereeled upon the reel member 82.

The gathering member comprising the tines: 28 etc. is then elevated up to a point substan tially near the reel 62. As the gathering mem-' her is elevated, the members 24 and 32 are likewise pivoted upwardly and it is then necessary 7 to trip the gathering member to release the manure off of the tines 28. This is accomplished by turning the wheel 58 through the agency of the handle By turning the whee1 58, the steering post 48 is rotated which rotates the worm in the casing 48 which correspondingly causes the worm gear at 41 to rotate and in turn swings the lever 44 in the direction of the arrow 80.

This forces the lever 42 upwardly which through pivotal engagement at 4| with the lever 40, which lever 40 is attached to the shaft 31,

; wardly thereby rotating the members 26 about the pivots which swings the tines 28 down wardly and allows the manure to be released on to the top of the stack or at any desired location.

After the load is raised, the brake can be ap- This causes the and moves the pivot attached at 11 to the brake band I8. This causes the brake band to be tight- 1 ened against the brake drum 88 since the other end of the brake band is rigidly attached at 'H to the frame. The tightening of the band against 1 the drum causes locking of the shaft 81 which 1 through the gear arrangement locks the reelj member 82 so that as a result, the arrangement can be elevated to any position and locked thereat, and during raising or lowering of the unit 2,242,982 1 tending plate 21. The shaft 8| extends into the the brake can be applied gradually or quickly as desired.

The tines 28 are brought to horizontal position by reverse movement of the wheel 58. and in this manner, any angular positioning of the tines can be effected and through the foregoing reeling structure the gathering member can be elevated to any desired height. As explained heretofore, the outwardly projecting lips 88 which are an integral portion of the member 58 prevent the side bars 24 from passing beneath such members. All of these operations can be readily performed from the rear seat 84, which is indicated in dotted lines in Figure 1 to prevent confusion, since the wheel 58 is directly adjacent thereto.

A further modification is shown in Figure 5 wherein the upper bars 32 are attached to rods 82 which rods are attached within pistons engaged within hydraulic cylinders 83. The cylinders 83 are attached to a bracket 84 which is pivoted at 85 to a further bracket 86 which is attached to the rear axle housing which is inditlagted generally as explained by the character the pipes 81 which pass to the rear of the cylinders 83 and further pipes 88 which pass to the forward ends of the cylinders 83. The pipes 81 are connected to cylinders 88 and the further pipe 88 to the cylinders 80 which cylinders include suitable pistons attached to the handles 8| and 82. An auxiliary oil tank is indicated by the character 83. Through the foregoing arrangement, the pressure can be applied either wardly or rearwardly so that as a result, the samepivoting can be applied to the bars 32 to raise or lower the'tines' 28 without the necessity of apparatus of steering post etc. as explained heretofore. This arrangement works on hydraulic principles and the application of pressure through the handles 8| and 82 will correspondingly cause cooperative action to the bars 32.

It will now be seen that we have provided a manure loader which can be attached to a standard tractor, which can be raised or lowered from the same. which can be held in any elevated position and which can be powered directly from the power take-off of the tractor, which can be utilized in any position and which can be manufactured at a simple cost.

Some changes may be made in the construction and arrangement of the parts of our invention without departing from the real spirit and purpose of our invention, and it is our intention to cover by our claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
